Flash Player 5; behavior changed in Flash Player 7.
my_mc.loadVariables(url:String [, variables:String]): Void
url The absolute or relative URL for the external file that contains the variables to be loaded. If the SWF file issuing this call is running in a web browser, url must be in the same domain as the SWF file; for details, see “Описание,” below.
variables An optional parameter specifying an HTTP Метод for sending variables. The parameter must be the string GET or POST. If there are no variables to be sent, omit this parameter. The GET Метод appends the variables to the end of the URL and is used for small numbers of variables. The POST Метод sends the variables in a separate HTTP header and is used for long strings of variables.
Ничего.
Метод; reads data from an external file and sets the values for variables in my_mc. The external file can be a text file generated by ColdFusion, a CGI script, Active Server Page (ASP), or PHP script and can contain any number of variables.
This Метод can also be used to update variables in the active movie clip with new values.
This Метод requires that the text of the URL be in the standard MIME format: application/x-www-form-urlencoded (CGI script format).
In SWF files running in a version earlier than Flash Player 7, url must be in the same superdomain as the SWF file that is issuing this call. A superdomain is derived by removing the left-most component of a file’s URL. For example, a SWF file at www.someDomain.com can load data from a source at store.someDomain.com because both files are in the same superdomain of someDomain.com.
In SWF files of any version running in Flash Player 7 or later, url must be in exactly the same domain as the SWF file that is issuing this call (see "Flash Player security features" in Using ActionScript in Flash). For example, a SWF file at www.someDomain.com can load data only from sources that are also at www.someDomain.com. If you want to load data from a different domain, you can place a cross-domain policy file on the server hosting the data source that is being accessed. For more information, see "About allowing cross-domain data loading" in Using ActionScript in Flash.
If you want to load variables into a specific level, use loadVariablesNum() instead of loadVariables().
Вы можете расширять методы и обработчики событий класса MovieClip, создавая его подклассы. Для более подробной информации смотри "Присвоение класса мувиклип-символу " в Использовании ActionScript во Flash.
В примере ниже loads information from a text file called params.txt into the target_mc movie clip that is created using createEmptyMovieClip(). The setInterval() функция is used to check the loading progress. The script checks for a variable in the params.txt file named done.
this.createEmptyMovieClip("target_mc", this.getNextHighestDepth());
target_mc.loadVariables("params.txt");
функция checkParamsLoaded() {
if (target_mc.done == undefined) {
trace("not yet.");
} else {
trace("finished loading. killing interval.");
trace("-------------");
for (i in target_mc) {
trace(i+": "+target_mc[i]);
}
trace("-------------");
clearInterval(param_interval);
}
}
var param_interval = setInterval(checkParamsLoaded, 100);
/* params.txt includes the following text
var1="hello"&var2="goodbye"&done="done"
*/
